Which best describes a convex structure in dental terms?

In dental terminology, a convex structure is best described as being bulged or curved. This means that the surface of the structure curves outward, creating a bulging effect. Examples of convex structures in dentistry include certain types of dental crowns, dental restorations, and the buccal surfaces of teeth that are rounded outward. These convex shapes can be important for both functional purposes, such as allowing for proper dental occlusion, and for aesthetic reasons, as they provide a natural appearance to the teeth. The curvature associated with convex structures can also aid in distributing occlusal forces evenly across the surface, which is critical for maintaining oral health.
